I have an interview for a postdoc position in Mathematics at a very good university in the UK. The interview committee comprises a maths professor (not in my field, which is analysis of PDEs) and three other professors from other scientific disciplines.
I do not expect any technical questions since they are not in my field. But I am worried they will ask me: "why is your work important/useful/relevant?" in the context of applications to real-life. What can I say in such a situation? Also does anyone have any general advice to what such a panel might ask me?
